Representatives for the legendary rock band KISS announced Sunday that the band has been forced to postpone its upcoming Japanese tour dates in April. Tickets will not be going on sale March 12th, as previously announced, and the dates will be rescheduled. Once the new dates are released, they will be revealed on KISSonline.com. The band is scheduled, meanwhile, to hit the studio in March or April to begin work on its 20th studio album, which they hope to have in stores before the end of the year. The band's last album, "Sonic Boom," sold 108,000 copies in its first week of release to land at No. 2 on the Billboard 200 albums chart, the highest spot reached in the band's illustious 25-and-counting-year recording career.
